We often act like babies when we want to be happy. Why? I think it is because children have no worry and they don’t complain.

We can set a goal in our life and go after what we want. But if we’re  ①   all the time, how can we live happily? If you don’t believe me, count how many ①   you complain about something in one day. Whether it is being trapped in busy traffic or troubled by weather, or whatever it is, there are endless things you can find to complain about.

But it’s not just the outside condition that we will complain about. We complain about ourselves too. We complain that we don’t have enough time or money, and that we’re not smart enough, cool enough, or just enough. Many times we experience lots of unpleasant things because of complaining about things we can’t control.

Think about how much happier you would be if you stopped complaining? ②Much of what you complain about is out of your control anyway. What’s the meaning of thinking about something you have no power to change?

Finding out what you are complaining about is the first step to stop complaining. Ask yourself if you prefer to complain or to be happy.

It’s best to stop to enjoy the beautiful life, but not to waste time to complain.
